    Summary
    This summary is machine-generated.

    A simple bimalleolar ratio test can reliably predict ankle fractures, questioning the routine use of X-rays for all ankle injuries. This method aids in efficient fracture diagnosis.

    Area of Science:

    • Orthopedic Surgery
    • Radiology
    • Sports Medicine

    Background:

    • Routine X-ray imaging of all injured ankles is a common clinical practice.
    • There is a need for cost-effective and efficient diagnostic methods for ankle injuries.

    Purpose of the Study:

    • To evaluate a simple measurement to predict the likelihood of ankle fractures.
    • To assess the necessity of routine X-ray imaging for all ankle injuries.

    Main Methods:

    • A bimalleolar ratio was calculated by comparing the diameter of the injured ankle to the uninjured ankle.
    • This ratio was used to determine the presence or absence of fractures.

    Main Results:

    • A bimalleolar ratio above 1.065 reliably indicated a fracture.

    Related Experiment Videos

  • 62% of patients had ratios below 1.065 and showed no fractures, suggesting unnecessary X-rays.

    • Conclusions:

    • The bimalleolar ratio is a reliable, simple method for predicting ankle fractures.
    • This measurement can help reduce the overuse of X-rays in diagnosing ankle injuries.
